Cycle 0 DCO+ (black) and C18O (gray) PV diagram. Cuts are made at PA = 26° for DCO+ and PA = 35° for C18O. Keplerian (solid line) and Infall plus Keplerian (dashed line) rotation PV models with M = 0.2 M are overplotted (Murillo et al. 2013). Contours are in steps of 3, 3, 5, 10 and 15σ with σ = 19 mJy beam-1 for C18O, 7, 5, 3, 2, 2, 3, 4, 5σ with σ = 12 mJy beam-1 for Cycle 0 DCO+.
